I don't really think this would count as a solution, but it is an interesting technical challenge.

I own a bunch of small, very powerful lasers (intended for engraving) that would have a high chance of not just dazzling a camera, but permanently damaging it. I wonder how feasible it would be to build a system that can physically locate a moving drone with enough accuracy. Maybe by tracking its RF signals?

Hmm, this might be a fun project, purely for intellectual purposes. I also own a bunch of RC aircraft that I could use as targets...
